CROSS REFERENCE TO RELATED APPLICATION

The present application claims priority to Chinese Patent Application No. 202011112533.0, titled “APPLICATION WHITE BOX DEVICE UTILIZED IN CONJUNCTION WITH INTELLIGENT TERMINAL”, filed on Oct. 16, 2020 with the Chinese Patent Office, which is incorporated herein by reference in its entirety.

FIELD

The present disclosure relates to the technical field of communications, and in particular to an application white box device utilized in conjunction with an intelligent terminal.

BACKGROUND

With continuous development of Internet information technology, intelligent terminals are widely used in daily production and life. For example, general-purpose intelligent terminals are used in the technical field of Internet of Things. With the development of the Internet of Things technology, general-purpose intelligent terminals cannot meet specific use requirements. Therefore, an intelligent terminal is to be customized and developed for specific use requirements. Practically, a scale of customizing and developing one intelligent terminal, for example, customized and developed for specific use requirements of only one user or a few users, is relatively small, resulting in a high cost of customizing and developing the intelligent terminal, and thus restricting promotion and popularization of the Internet of Things technology.

In addition, a user may have different security requirements for the intelligent terminal in different application scenarios. Therefore, if one intelligent terminal cannot meet security requirements of the user in different application scenarios, the user may require different intelligent terminals. For example, in one scenario, security authentication is unnecessary and therefore an intelligent terminal A is used. In another scenario, security authentication is required when accessing data and an application of the intelligent terminal, and the intelligent terminal A is not provided with hardware related to security authentication. Therefore, only an intelligent terminal B provided with hardware related to security authentication can be selected. It can be seen that access security of the intelligent terminal restricts application of the intelligent terminal. An intelligent terminal without hardware related to security authentication has low security in accessing data and running an application.

It is apparent that the described embodiments are only some rather than all embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without any creative work fall within the protection scope of the present disclosure.

White box refers to decoupling between software (for example, data, application and system) and hardware (intelligent terminal). Particularly, an application white box refers to decoupling between applications and an intelligent terminal. That is, the applications are all installed in a white box device and are not installed in the intelligent terminal.

FIRST EMBODIMENT

Reference is made to FIG. 1, which is a schematic structural diagram of an application white box device utilized in conjunction with an intelligent terminal according to an embodiment of the present disclosure.

As shown in FIG. 1, the application white box device utilized in conjunction with an intelligent terminal according to the embodiment of the present disclosure includes a controller 101, a memory 102, and a subscriber identity module (SIM) unit 103. The memory 102 may include a data storage space 1021 and an application storage space 1022. Both the memory 102 and the SIM unit 103 are connected to the controller 101. In a case that the application white box device is utilized in conjunction with the intelligent terminal, the controller 101 is connected to the intelligent terminal. In an example, the controller 101 may communicate with the intelligent terminal by utilizing a data transmission protocol of SD3.0, or a data transmission protocol with a transmission rate higher than that of SD3.0.

It should be noted that, the controller 101 is configured to provide support for management of the memory 102 and call of the SIM unit 103. The memory 102 is configured to provide a physical medium for storing data and an application of the intelligent terminal. The SIM unit 103 is configured to provide support for encryption and security authentication of the data of the intelligent terminal. In addition, the memory 102 is further configured to provide a physical medium for presetting and installation of the application of the intelligent terminal. The SIM unit 103 is configured to provide security support for operation of the application. It should be noted that the memory according to the embodiment of the present disclosure can meet various storage requirements rather than being limited to data storage. In an example, the memory 102 may include the data storage space 1021 and the application storage space 1022. Data is stored in the data storage space 1021, and the application is installed in the application storage space 1022.

In the technical solutions of the present disclosure, the intelligent terminal refers to a terminal device which is capable of computing, storing and communicating, and is provided with a sensor and an input and output interface. In an example, the intelligent terminal may be a portable intelligent terminal such as a mobile phone, a tablet computer, or a headset. Alternatively, the intelligent terminal may be an Internet of Things terminal. A type of the intelligent terminal is not limited herein.

In an example, the Internet of Things terminal may be any one of a camera, a vehicle-mounted intelligent terminal, an intelligent three-meter (including an intelligent water meter, an intelligent electric meter, and an intelligent gas meter), and an industrial control terminal.

For the application white box device according to the embodiment of the present disclosure, white box indicates that the intelligent terminal is utilized in conjunction with the application white box device and therefore data originally required to be stored in the intelligent terminal can be stored in the application white box device, and an application originally required to be installed and run in the intelligent terminal can be installed and run in the application white box device. That is, the application white box device causes the intelligent terminal connected to the application white box device to be white boxed.

For example, in a case that the intelligent terminal is the mobile phone, data and an application in the mobile phone is stored in the memory of the application white box device. A hardware unit (SIM unit) with security authentication in the application white box device can protect the data and the application in the mobile phone. Since the application in the mobile phone is installed in the memory of the application white box device, the user is required to be permitted through the security authentication of the SIM unit to access the application. In a case that the mobile phone is lost, nobody except the user can crack the security authentication of the SIM unit, thereby protecting the security of the data and the application in the mobile phone.

The application white box device is configured to implement at least one of an application access function, a data storage function, a data transmission function and a data access function.

Next, the application access function, the data storage function, the data transmission function and the data access function implemented by the application white box device are described respectively in detail.
